Combining an autoactivated cGAS mutant with membrane-tethered IL-12 via mRNA lipid nanoparticles promotes systemic tumor control

Local tumor therapies rarely induce systemic immunity capable of controlling metastatic disease. Here, we engineer an mRNA lipid nanoparticle (LNP) platform to coordinate innate immune sensing and T cell activation in situ through co-delivery of an autoactivated cyclic GMP-AMP synthase mutant (cGASR241E) and membrane-tethered IL-12 (IL-12TM). cGASR241E mRNA LNPs autonomously generated cyclic…
